2022 Projects: Drones for Yield Predictions and N Management Decisions

How Best to Use of Unmanned Aerial Systems (UAS) for Management of Corn and Sorghum?

Precision agriculture is moving toward the implementation of technology-driven farm management packages that also help with making better decisions about crop fertility management (decision agriculture). Of all nutrients essential for crop growth, N is most difficult to manage due to varying crop N demands throughout the season and inability to accurately predict N supply. Use of drone-obtained NDVI images has the promise to aid in quick and accurate decision making for better N management of field crops like corn and forage sorghum that have large and well-timed N needs but requires accurate estimation of (1) end-of-season yield; (2) soil N supply; and (3) crop N needs. Our overall objective here is to evaluate use of drone-collected images as tools for predicting yield and N needs for both crops.

    Our goals are to evaluate use of drone collected images for yield predictions of N responsiveness and needs for corn and forage sorghum as impacted by timing of flight (in the day and over the growing season).
